.IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 123,539, dated February 6, 1872.

To all whom it may concern:

Be it known that I, Asn W. WILKINSON, of the city, county, and State of New York, have invented a new and useful Improvement in Oarbureters; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing- Figure l represents a vertical central section of my invention in the pla-ne 00 a', Fig. 2. Fig. 2 is a horizontal section of the same.

Similar letters indicate correspon di n g parts.

This invention relates to an improvement in that class of carbureters which contain a spiral passage lined with cloth or other absorbentmaterial, so that the gas which is to be carbureted, when passed through the spiral passage, is

brought in contact with the hydrocarbon spread over an extensive evaporating-surface, a-nd thereby the desired object is attained. Myiniprovelnent consists in the arrangement of a series of nozzles provided with stop-cocks and leading each into one of the spaces or coils of the spiral passa ge,in combination with the pipe which is intended to carry oft' the carbureted gas, in such a manner that, by means of the stop-cocks and nozzles, the gas can be drawn oi from either of the coils ofthe spiral passage, and the quantity of hydrocarboli-vapors taken up by said gas can be controlled.

In the drawing, the letter A designates a vessel, from the top or cover B of which is suspended a coil, C, made of sheet metal or other suitable material and lined with cloth, lampwick, or other absorbent material. Through said top, and near its circumference, passes the feed-pipe D, by which the gas to be carbureted 1s introduced into the apparatus. E is the discharge-pipe, Which connects with the interior of the vessel A by a series of nozzles, F, which lead into the spaces between the coil C, (see Fig. 1,) and each of Which is provided with a stop-cock, a.

The vessel A is filled with hydrocarbon liquid, and the gas to be carbnreted, on being admitted through the pipe D, comes in contact with the surface of the hydrocarbon liquid, and also with the lining of the coil, which is saturated with the hydrocarbon liquid, and, while passing' through the spiral passage formed by the coil O, the gas becomes carbureted. The distance through which the gas is allowed to travel through the spira-l passage is regulated by meansof the stop-cocks a. If the cock nearest to the feed-pipe is opened the gas will travel only through one coil ofthe spiral passage, and it will take up a proportional amount of hydrocarbon-vapors; and by closing this cock and opening the next the gas is con'ipelled to travel through a greater portion of the spiral passage, and by these means the quantity of hydrocarbon-vapors taken up by the gas can be regulated; and, particularly as the quant-ity of hydrocarbon liquid in the vessel A diminishes, the regulating-cocks and nozzles become of great importance, and I am enabled to control the quality of the gas-mixture with accuracy under all circumstances.

W hat I claim as new, and desire to secure by Letters Patent, is-

'lhe regulatin g-nozzles F, in combination with the coilO, vessel A, feed-pipe D, and discharge pipe E of a carbureter, substantially as herein shown and described.
